Application led May 23, 1916. Serial No. 99,352.

To all whom t may concern.'

Be it known that l, RUrUs A. PARENT, a citizen of the United Statesl ofAmerica, residing at South Tacoma, in the county of Pierce and State oflVashington, have invented certain new and useful lmprovements inChair-Braces, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates to chair braces and has for its object theproduction of a simple and ellicient means for connecting the four legsof a chair so as to prevent the legs from spreading outwardly underundue strain.

Another object of this invention is the production of a simple andeflicient means for facilitating the tightening of the braces or theadjustment thereof to take up any slack therein in order that theoutward spreading of the legs of a chair may be averted.

Vith these and other objects in view this invention consists of certainnovel combinations, constructions, and arrangements of parts as will behereinafter moi'e fully described and claimed.

ln the accompanying drawing: Figure 1 is a sectional perspective view fa chair, the bottom and forward legs thereof being shown in section forfacilitating the illustration of the bracing mechanism. Fig. 2 is acentral transverse section through the chair legs. Fig. 3 is a sectiontaken on line 3-3, of Fig. 2. perspective of the central connectingmeinber. Fig. 5 is a detail perspective of the upper suspending member.Fig. 6 is an enlarged transverse section through one of the legs showingthe guiding bracket or plate for engaging the bracing wires and holdingthe same around the leg of a chair. Fig. 7 is a detail perspective ofone of the guiding plates illustrated in Fig. 6. Fig. S is a detailperspective of one of the hanger plates carried by the seat of thechair. Fig. 9 is a detail perspective of a modified form of the wirebrace guiding plates which may be substituted for the structure shown inFig. 7 if so desired.

Referring to the drawing it will be seen that 1 designates the seat ofthe chair which is provided with suitable legs 2. A plurality of hangerplates 3 are secured to the seat 1 by having their overhanging ends 4Fig. t is a detail inverted fastened to the top of the seat 1 by meansof the pins 5 as illustrated in Fig. 1 of the drawing. Flach hangerplate 3 is provided with an inwardly projecting hanger end 6, whichhanger end 6 is provided with an elongated aperture 7, through whichaperture 7 passes a loop of the hanger wire 8. One of these plates 3 iscarried by each side of the bottom 1 of the chair as illustrated in Fig.1, and the hanger wire 8 is passed through the apertures 9 formed in theupwardly extending flanges 10 of the hanger plate 11. The free ends ofthe hanger wire 8 are then twisted together as indicated by the numeral12 in Fig. 1 to constitute an eilicient securing means for the hangerwire 8.

A hanger bolt 13 passes through the centrally located aperture 1l in thehanger plate 11, and this hanger bolt 13 is provided with a thumb nut 15threaded upon the lower end thereof as illustrated clearly in Fig. 3,whichnut 15 engages al washer 1G as illustrated in Fig. 3. rl`he hangerbolt 13 passes through a central connecting plate 17, and this centralconnecting plate 17 isprovided with a plurality of depending flanges 18having apertures 19 formed therein, through which apertures 19 pass thediverging bracing wires 20. The free ends` of the bracing wires 20 aresecured together as indicated by the numeral 21 in Fig. 2. The divergingportions 20 of the bracing wire are wound around the legs 2 of the chairto constitute a loop 22 as illustrated clearly in Fig. 6, and this loop22'also passes through the rolled portion 23 of the guiding plate 24.The guiding plate 24 is provided with a depending flange 25 having anaperture 26 formed therein, and the parallel strands of the bracing wire20 pass through this aperture 26 as illustrated clearly in Fig. 6 of thedrawing, thereby holding the strands of the bracing wire 20 insubstantially parallel relation with respect to each other. It should beunderstood that the bracing wire 20 is passed around each leg in asimilar manner to that illustrated in Fig. 6. It should be understoodthat the central connecting or junction plate 17 may be adjustedvertically upon the hanger bolt 13 by screwing the thumb nut 15 upwardlyupon the bolt 13, thereby tightening the bracing wires 20 and tending todraw the lower ends of the legs 2 inwardly and in this manner it will beseen that the legs 2 may at all times be kept eiiiciently braced bymeans of the bracing cable 20.

In Fig. 9 there is shown an embodiment or modified form of the guidingplate 2a, wherein the guiding plate comprises a body 27 having a rolledportion 28 through which the loop 22 of the wire is adapted to pass, andthis body portion 27 is provided with upwardly turned ears 29, underwhich ears are adapted to pass the parallel strands of the wires 20 aswill be obvious by considering Figs. l and G of the drawing.

It should be understood that the present device may be very cheaplymanufactured, and that any part thereof may be readily replaced when sodesired, and it should be further understood that the device may beapplied to any suitable or desired chair without materially changing theconstruction thereof.

Having thus described the invention what is claimed as new, is:-

l. In combination with a chair provided with a bottom, a plurality ofhanger plates, a hanger wire connected to said hanger plates, a junctionplate, a bracing wire, said junction plate provided with a plurality ofdepending flanges, each flange provided with an aperture formed therein,said bracing wire provided with a plurality of diver-ging strands, thestrands of said wire passing through said apertures, guiding platesmounted upon the diverging ends of said strands, said strands beingwound around the legs of said chair to constitute a loop, each guidingplate provided with a rolled Copies of this patent may be obtained forve cents each, by addressing the portion engaging said loop, and eachguiding plate provided with means straddling said strands for holdingthe diverging strands against accidental displacement from the legs ofsaid chair.

2. As a new article of manufacture, a chair brace comprising a hangermember, a junction plate, a bracing wire adapted to be secured to thelegs of a chair, said bracing wire comprising a plurality of pairs ofdiverging strands, each pair of diverging strands terminating in a loopat the outer end thereof for fitting around the leg of a chair, aguiding plate provided with a rolled portion engaging said loop, eachguiding plate provided with a depending iange having an aperture formedtherein, and said strands passing through said aperture for holding thestrands of each pair in substantial parallel relation. Y

3. As a new article of manufacture, a chair brace comprising a hangermember, a junction plate, abracing wire carried by said junction plateand provided with a plurality of pairs of diverging strands, each pairof strands provided with a loop adapted to engage the legs of a chair, aguiding plate carried by each pair of strands and provided with a rolledportion engaging said loop, and each guiding plate also provided with aplurality of folded ears for constituting guiding means for holding thestrands 0f each pair in a substantial parallel relation with respect toeach other.

In testimony whereof I hereunto signature.
